Is there a trick to landing slow on this guy? 65 Chanter, 65 Cleric, 65 Wizard (me) were trying to trio him but the chanter couldn't get slow to stick. He had like 12 resists in a row and Glyk was tashed. Cleric couldn't keep the pet (war boar) alive without slow and we died on every attempt. I'd appreciate a response from a chanter who's been able to slow Glyk with how you got it done.
Thanks in advance.
